My BTA split, not sure what it means

[stanleo]

So day before yesterday I had one BTA that looked happy and yesterday all of a sudden I have two smaller ones of equal size. Does this mean it was healthy and happy or is something wrong? Is there anything I should look out for?

Last tests were done on Wednesday of last week. Doing another round today.
Temp 78F
Salinity 35 ppt
pH 8.1 API
Alkalinity 9.5 dKH Red Sea
Calcium 440 ppm Red Sea
Magnesium 1560 ppm Red Sea
Phosphate .3 ppm Salifert
Nitrate 2 ppm Salifert

Sometimes they do that when they're healthy. Mine have split several times.

Healthy ones can do that, a ph swing has been known to cause splitting also.

Definitely can be because of good health or stress. Hard to tell really.

My original has split about 9 times so far in a year and a half. I'd consider it normal if you have an established tank with appropriate flow and lighting.
